Patent EP-0296430-A3 (EP)
IPC: G06F12/0864
Filed: 1988-06-10
Abstract: A computer memory management method for cache 
memory (10) uses a deconfirmation technique to provide a 
simple sequential prefetching algorithm. Access 
sequentiality is predicted based on simple 
histories. Each memory line in cache memory is 
associated with a bit in an S-vector (20), which is 
called the S-bit for the line. When the S-bit is 
on, sequentiality is predicted meaning that the 
sequentially next line is regarded as a good 
candidate for prefetching, if that line is not 
already in the cache memory. The key to the 
operation of the memory management method is the 
manipulation (turning on and off) the S-bits.

Patent EP-0326973-A3 (EP)
Title: Piezoelectric laminate and method of manufacture
IPC: H01L41/257
Filed: 1989-01-28
Abstract: A piezoelectric laminate comprises a piezoelectric layer and an insulating substrate layer rigidly bonded thereto. During poling, conditions are established under which a poling potential is established at the boundary of the layers which insures that a substantial part of the poling voltage is dropped across the piezoelectric layer. The poling voltage is maintained for a period greater than the time constant under the poling conditions of the material to which the poling voltage is applied. In one embodiment, the poling conditions are achieved by substantially enhancing the conductivity of the substrate layer relative to that of the piezoelectric layer. In a second embodiment, an intermediate bond layer is selectively switched from a non-conductive to a conductive state in response to a selected stimulus so as to form an electrode for facilitating the application of a poling field directly across the piezoelectric layer.

IPC: C22B1/00
Filed: 1989-12-15
Abstract: Both aluminum scrap covered with a volatile 
coating and a heated airstream having a low oxygen 
content pass through a kiln (2) where the airstream 
causes the coating to volatilize. The temperature 
of the airstream, where it enters the kiln, is 
maintained essentially constant, slightly below the 
melting temperature of the aluminum, and likewise 
the temperature of the airstream is maintained es­
sentially constant where the airstream leaves the 
kiln (2) , this being achieved by varying the mass flow 
of the airstream to compensate for variances in the 
nature and mass of the aluminum scrap within the 
kiln (2). Beyond the kiln the airstream enters an 
afterburner (8) where it is heated in the presence of 
sufficient oxygen to effect combustion of the volatile 
components of the coating. The airstream then passes 
through a heat exchanger (12) and back to the kiln (2). The 
mass flow within the kiln (2) is controlled by diverting 
some of the airstream upstream from the heat ex­
changer (12) or by varying the speed of the fan (6) which 
creates the airstream.
